>>221 - good sleuthing skills!
He isn't on any list I have seen on Twitter as a presenter. In fact #Oscars2016 and #tomhiddleston searched together throws up one girl saying he is her perfect Oscars date and a few posts from October last year saying "no Oscar for ISTL now it's been put back." Sob.
Last year he was at Nuffield on Oscars night. I am sure if he wanted he could get an invitation. That kind of says to me he would prefer to attend only as a presenter or as a nominee. BAFTAS I think may be a bit different - local boy, involved in their fundraising dinners and last year was a presenter. He is also a bigger fish in a smaller pond, so he can probably always get a presenting gig at the BAFTAs if he wants one.
